T 0 all whom it may com-Hm:

Be it known that I, :iTEFANUS NIELSEN,.

device for moving the ribbon to cover and uncover the printing point.

One ob 'ect of my invention is to provide a construction wherein a ribbon having a plurality of fields .of different characteristics may, at a u'inting operation, be moved to cover the printing point with any desired field of the ribbon. I

Another object is to provide means to dispense at will with the crosswise feed of the ribbon in that class of machines employing a ribbon vibrator and wherein the ribbon has .both a crosswise and a lengthwise feed.

A further object is to provide means to enable a ribbon of more than one color to be employed in the lastnamed class of ma chines.

Other objects will subsequently appear. To the above ends thcinvention resides in the features of construction, combinations of devices and arrangements of parts to be hereinaftermore full described and particularly pointed out in t e appended claims.

In the accompanying drawings, Figure 1 is a vertical front to rear sectional view, taken about centrally, of one form of typewriting machines embodying my invention. Fig. 2 is a fragmentary front elevation showing the upper portion of the machine. Fig. 3 is a rear view taken on a plane represented by the line {6 in Fig. 1, various parts being omitted; Fig.- 4:.is an enlarged fragmentary top plan view showing parts of the ribbon mechanism. Figs. 5 and 6 are views similar to Fig. 4 but showing various parts in differ.- cnt positions from those in whichthey ap-. pear in said Fig. 4. I My invention is shown as embodied in a Monarch typewriting machine butit may be adapted to other forms of writing machines.

In the drawings, 1 is the base of themachine supporting corner posts 2, which sus tain-a top plate3; 'Key levers 4; are fu l-.

crumed on a fulcrum plate 5 andeach key lever is provided with a restoring spring 6'. I Pivoted at .7 to each key lever. is a sub-lever 8, the lower portion whereof co-acts with afixed abutment 9 and then per portion whereof is connected by a lin "10' with a type bar 11 which is one of a segmentall-y arranged series. Each type bar 11 is seated in a radial slot 12 formed in a segmental type ing perforated to receive a segmental pivot the top face of the segmental support 13. Instead of this mode of pivoting the type bars on a fulcrum wire they may be provided with separate hangers and pivots. The type bars are normall supported at their free ends by a segmental type rest 15 and said bars are adapted 'to cooperate with a platen 16- mounted in a carriage 17, said carriage. being guided and supported by anti-friction balls 18 which are seated in grooved rails 19 on the carriage and in oppositely grooved rails 20 mounted on brackets 21 which are fixedly secured to the top plate 3. The carriage 17 is provided with a feed rack 22 which normally meshes with a pinion 23, the latter being operatively connected with an escapement wheel 24. j

Adapted to cooperate with the escapement dog rocker 26 which has a horizontal arm 27 ,connected by arod. or link 28 with the rearwardly extending arm 29 of a universal bar frame 30 pivoted in the base of the machine at 31 (Fig. 3) The frame 30 carries auniversal bar 32 whichextends from side to side of the machinebeneath the s acing levers (not shown) and the series of and is adapted to be actuated'by said'l'evers when the latter aredepressed as happens during each printing or spacing operation. The carriage 17 is connected by a" stra -33 with a spring drum 34 which tends to raw the carriage to the left sothat when the universal bar 32 is actuated. the escaemen-t mechanism just described is cause to' be operated in a-known manner'a-nd thereby to permit of letter space movements of the carriage.

Ribbon spools-35 arranged above the top plate 3 at each side of the machine and forwardly of the platen, receive a ribbon 36, which, as herein shown, is divided" Lon itudi nally into fields a and b ofdifferentc aracbar support 13, the heels of the type bars be-' wire 14 which is contained in a groove cut in wheel are feed dogs 25 mounted on-a pivoted ey levers 4,

teri'stics, that isto say, the field a ma be of one color such as black, and the fie d b of another and difierent color such as red, or

the field a, maybe copying ribbon and the field '1) record ribbon etc. The" ribbon 36 *may be fedlongitudinally-from either spool to the other by any suitable means.-

' The drawings illustrate"-a' ribbon feed mechanism which is similar to that employed Felbel &Oar l Gabrielson No. 7 03,339, dated. June 24, 1902.. Each ribbon spool 35'is car ."the pinion 46 being so connected with thein the Monarch typewriting machine and which is explained in U. S. Patent to J acob ried byand moved. with 'an upright shaft 37 which rotates in'a fixed bearing 38 and has secured at its lower end a small beveled gear 39. The gear 39 meshes with a beveled pinion 40secured to theforward end of a horizontal shaft 41, Which shaft carries at its rear end a beveledpinion 42 which is adapted'to mesh .',with a beveled driving pinion 43 mounted on a driving or power shaft 44. Rotary movement is transmitted to the shaft44 by beveled pinions 45 and'46, the pinion 45 being opera :tively connected with the driving shaft and spring dru'm 34'as to rotate with thelatter onlyduring the movement of the carriage 17 inletter space direction. It will be understood that. both ribbon spools are'connected ,with similar gear trains which are-adapted to be actuated from driving pinions 48 on the drivingshaft 44. As explained in the above cited atent the vdriving or power shaft 44 is capab e of longitudinal movement, and it isfurther to beunderstoodthat the longitudie nal position of said shaft determines which driving pinion'43 will be in mesliwith its cooperating pinion 42 and which ribbon spool will-be turned to wind the ribbon-thereon.

' Midway between the ribbon s ools theribbon 36 is threaded through a 'n bon vibrator or carrier 47 the lower end whereof is pro vided'with a vertical slot 48 and is shoul 'dere'doff at'49. Aloop 50 is secured at the rear of the lower portion of the vibrator. The vibrat or 47',is guided and supported in' the upright'arms 51 of the supporting bracket. 52, the latter being secured to the top late by (lie of the Secured to the under s1 top plate inrear of the bracket 52 isa downwar 1y depending lug 54 which isiformed with a pairof rearwardlyand downwardly rojeetin ears 55. An 0' erating lever 56 is pivotal y secured at 57 in the lug 54-and screws 53.

the forward end of said operatin v lever is adapted to play in the slot 48 in t e'ribbon vibrator and saidforward end is proyided' with a cross pin 58 which en ages with the loop 50 at the'rear of saidvi rator. A re-- storing s ring 59 vertically disposed at the rear of t e ribbon vibrator has one end secured to the latter and the other end secured in the forward end of the operating lever 56. The rear armof the operating lever is tion 68 and enters an elongated formed with an elon ated slot '60 with which eng'a es a pin or stu 61 secured-in the top of a in The'link is provided near its controller designatedas a whole by the nu me'ral which is 'slidably mounted upon the driving shaft 44 and which is normally adapted to cooperate with the strap formed by the link 62 and its bent arm 63. The

eccentric controller 65 comprises a compara-,

tively narrow eccentric working face 66, a

taperedor cam ortion 67 and a sleeve por- ,tion 68, which atter isfo'rmed with a circumferential groove ordepression 69 (Fig. 3). .A screw 70 passes into the sleeve porslot 71 in the power shaft 44. T e eccentrio member 65 is thereby slidably connected with the driving ..or power shaft 44 and is caused to rotate with said shaft, but may be 'moved'longitudinally of said shaft without affecting. the latter. The driving shaft 44 -m'ay also bemoved longitudinally without affecting the member 65.

1 The longitudinal movement of the eccen tric member 65 is controlled by a positioning or switching member or slide 72, which comprises first a vertically disposed arm 7 3, termi- 1 05 nating at the to in a perforated colla'rportion 74 and at the ower end in a fork 75 which partially surrounds the depression 69in the member 65, and second, a short obliquely disposed .arm- 76 (Fig. 1) terminating atits lower end in a fork 77. "A ull and push rod 78 has its inner end fixed y secured in the 'collar portion 74 of the ositioning member or slide 72 and bears in t change of the top plate 3,;passing through the latter and. ter-, minating exteriorly of the'machi ne in afin gerbutton 79.. The rod 78 is formed with notches 80, 81 and '82 with which a locking roove or spring 83 is adapted to engage, saidlocking spring being. secured to the top plate by a screw 84'. The rod 78 also has a bearing in a .lug 85 depending from the top plate, which lug'serves' also as one ofthe bearings of the driving shaft 44. Q

The ears 55 of the lug54 are perforated 'to permit of the passage of a horizontal rockshaft 86. which is .slidably mounted in said ears, and, as viewed from the rear, terminate at the left end in a head 87. Just outside. the left handear 55 (Fig. 4).the shaft 86 is embraced by the fork 77 of the arm 76.

an elongated slot 94 wil Fixedly secured to the shaft '86 between the ears is a rearwardly projecting lever arm 88 which terminates in a horizontally disposed lip or ledge 89. I A forwardly projectmg .lever arm 90 terminates at its forward end in a hook portion 9l,'the two arms of which lie beneath the shoulders 49 of the vibrator 47, and at the rear in a collar portion 92 which is perforated so as to permit of the passage of the rock shaft 86, which latter serves as a pivotal support for the said forwardly projecting arm 90. 'A screw 93 is screwed into the collar portion 92 and enters 1n the shaft 86. A coiled spring 95surrounds the rockshaft 86 between the arm 88 and the collar portion 92 of the arm 90, and, as viewed from the re er of the machine, serves normally to maintain the arm 90 against the inner face of the left hand car 55 and the arm 88 against the inner face of the right hand ear.

Depending from the under side of them plate is'a .lug 96 to which is secured one end of a restoring spring 97, the other end whereof is attached to the link 62; The spring 97 constantly tends to draw the pin 61 to the rear of the slot 60.

If a one-color ribbon is in use and it be desired to employ a twocolor ribbon, the latter may be substituted in a known manner.

With the two-color ribbon in place and the parts positioned as shown in Figs. 3 and 4, the ribbon will be fed; progressively crosswise during successive printing operations and some of the type impressions will be made upon the field a, which may, for eX- ample, e black in color, some impressions be made upon the field b which may, for example, be red in color, while yetother in1= pressions will be made partly upon one field and, partly on the other. Bythis mode of operation a variegated or parti-colored effect will be obtained which may be desirable in some styles of ornamental typewriting. In most forms of typewriting, however, it is desirable to print in one-color at a time. If, as

' suggested, the two-color ribbon be, as is most usual, a black and red ribbon and it be'desired to print only on the black field, the pull ,rod 78 is drawn outward (or to the left as viewed in Figs. 3 to 6', inclusive) until the locking sprin 83, which normally is in engagement With the first notch. 80, engages with the second notch 81.. As it moves outward the rod 78 carries with it the switching member or slide 72,

which in turn, by means of the fork 75, draws the eccentric member 65 leftward so to disengage the eccentric face 66 from the link 62 and its bent arm 68, whereupon the spring 97 draws the stud 61 towards the rear end of the slot.60. This leftward movement of the switching member 72 also brings the fork 77 into contact with the inner face of the head 87 of the rock shaft 86, but the latter is not caused to move longitudinally thereby at this stage.v The parts will be now in the position indicated in Fig. 5; The spring 97 maintains the link 62 at the furthest point possible from the fulcrum of the operating lever 56, so that during each printing operation the operatl ing lever is thrown upward to the same height, and the parts are soadjusted that this upward movement causes the upper por- I tion of the ribbon to cover the printing point and the path of the type impressions will be i in a straight line longitudinal of the ribbon field 1a., or the black field. If it be desired to print from the red field b of the ribbon, the pull rod 78 is drawn outward still further until the locking spring 83 engages with the third notch 82 in. said. rod. 'lhe-outward movement of the rod 78 causes a further out ward or leftward movement of the switching member 72 and the fork 77 of the latter being new in contact with the head 87 of the rock shaft -86, causes a leftward longitudinal movement of said rock shaft in its bearings in the-ears 55. The rear lever arm 88, which is fixedly secured to the rock shaft 86, participates in this longitudinal movement of the rock shaft 86 and is drawn bodily leftward, transversely of the lever 56, until the ledge or li 89 at the rear 'of said lever arm 88 isvertica ly under. the rear end of the operating lever 56. During-this movementthe rear lever arm 88 compresses the coiled spring 95- between the arm itself and the collar portion of the forward lever arm 90, which latter remains motionless during the positioning of the parts just described. The various parts will now be in the positions indicated in Fig. 6.

At each printing operation, the rear arm of the operating lever 56 acts upon the lip or ledge 89 and thereby causes the rear lever arm 88 to swing downwardly, rotatii'ig the rock shaft 86 in its bearings. The pin and slot connection between the rock shaft and the'forward lever arm 90 causes the latter to swing upward at the same time and its hooked portion 91 engaging with the shoulders 49 of the ribbon vibrator raises the latt er upwardly. The parts are so adjusted that this upward movement or throw of the vibrator brings the lower portion of the ribbon to the printing sions obtained by a repetition of the printing operation follow a'path which is in-a straight line longitudinalof the field 3), that is, the red' field of the ribbon.- It is apparent that the arms 88 and 90 form respectively the rear and forward arms of a second operating lever, the fulcrum whereof is the rock shaft 86, this fulcrum being nearer the point of application of the power than is the fulcrum 57 of the first operating lever 56. The same length of movement of'the power, that is the same downward movement of the link 62, causes a greater extent of movement-at the. forward point and the type impres-v a connection which enables the vibrator to be operated by the second lever without being interfered with by the slower moving first lever 56. When the second lever is inoperative and the vibrator is moved upward by lever 56 the shoulders 49 of the vibrator move upward away from the hooked portion 91 and the secondoperating lever remains motionless. Whether the vibrator is actuated by the lever 56 or by the second lever comprising the arms 88 and .90, in either case the light rest )ring spring 59 restores the vibrator from printing to normal position. If itbe desir d to again print upon the black field of the ribbon the rod 78 is pushed in until the locking spring 93, disengaging from the notch or depression 82, again engages with. the second notch 81. This causes the switch or slide 72 and the eccentric member 65 controlled thereby, to move inward or towards the right until they againattain the position indicated in Fig. 5, while at'the same time the rock shaft 86, under the influence of the compressed restoring spring 95, is moved longitudinally inward until said rock shaft is also restored to the position indicated in said Fig. 5. With the parts so positioned, the field a of-the ribbon, that is the black field, is moved to the printing point at each printing operation as hereinbefore explained. If the rod 78 be pushed further in until the locking spring 83 again engages with the first notch 80. in said rod, the parts will be restored to the po sitions indicated in Figs. 3 and 4, the tapered or cam portion 67 of the eccentric member 65 effecting an easy and certain'entrance intothe space between the link 62 and its bent arm 63 and thereby causing the eccentric facev 66to again engage with its strap. The

various parts are now positioned so as to again cause a progressive crosswlse feed of the rlbbon as herembefore explalned.

Various changes in the construction, ar.

rangement and combination of the parts may be efiected WltllOll't departing from the spirit of my invention.
